## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-r94f-hx44-8jqf. This link is maintained to preserve external references.

### Original Description
Grav CMS before 2.0.13 contains a remote code execution vulnerability in the Flex Objects plugin settings validation that allows authenticated users to execute arbitrary code by uploading a ZIP file containing PHP code. Attackers can bypass routine name validation by using array notation instead of string notation, call the unZip routine with a malicious archive, and write PHP files to the web root for execution.

## Affected packages

- `getgrav/grav < 2.0.13`

## Remediation

Refer to the advisory for the patched release.
